Copyrights on files

Someone has pointed out to me that we have non-PostgreSQL/Berkeley
copyrights on a number of files:src/port/rint.c* Copyright (c) 1999, repas AEG Automation
GmbHsrc/backend/port/dynloader/aix.c*This is an unpublished work copyright (c) 1992 HELIOS Software GmbH* 30159

Berkeley* All rights reserved.... BSD copyright text followssrc/backend/utils/mb/Unicode/UCS_to_GB18030.pl# Copyright

I have emailed Andrew Yu to see if we can remove his line, but I
question whether the other people can be reached.

How should we handle this?
